notes:
- Rendered through egui's own paint pipeline (egui_wgpu::Renderer::update_buffers + ::render) with an epaint::Mesh, NOT a hand-rolled wgpu pipeline — the stack under test is the real one.
- Whole outline tessellated as ONE compound lyon path in one tessellate_path call.
- Format deviation: Rgba8Unorm, not sRGB, to match C2 (vello requires it).
- AA is nominally 8x on both candidates — the highest sample count both name, so pin 4's identical-configuration requirement is met as stated. The mechanisms are NOT the same: this is a hardware multisample render-target attachment (hence the TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES request), while C2 uses vello's compute-shader AA into a sample_count:1 storage texture. Matching integers do not imply matching work or matching cost; this is immaterial to Round 1's capability verdict and material to Round 4's timings.
